Description
Technical field
The utility model relates to doll carriage, relates in particular to a kind of simple in structure, easy to operate doll carriage backrest adjustment mechanism.
Background technology
In doll carriage, when being taken, the baby has better comfort, back of seat on the doll carriage has the function at its angle of inclination of scalable usually, thereby makes the head of a family can be according to baby's needs back of seat be adjusted into that the baby lies low or the adaptation angle of sitting.At present, being seen on the market doll carriage backrest adjustment mechanism has multiple, combines control and regulation formula or the like with stay cord as stay cord control and regulation formula, metal bridge control and regulation formula and pull bar.Yet there is following common weak point in they:
1, structure is all too complicated, and amount of parts is many, the product assembling is loaded down with trivial details thereby cause, and has increased doll carriage weight, no matter be material cost, or the production assembly cost is all higher, badly influences the competitiveness of product in market.
2, existing backrest adjustment mechanism generally all needs bimanualness, and the position, operating station is lower, and the adult often needs to bend over to operate, and it is very inconvenient therefore to operate.
Summary of the invention
The utility model purpose is: a kind of simple in structure, easy to operate doll carriage backrest adjustment mechanism is provided.
The technical solution of the utility model is: a kind of doll carriage backrest adjustment mechanism, comprise vehicle frame and back support bar, the connecting element of described back support bar and vehicle frame is by the pin pin joint, the pin-and-hole of above-mentioned back support bar is a slotted hole, the bottom of back support bar is provided with dead bolt, be provided with stage clip between dead bolt and the pin, be installed with locations on the described connecting element, this locations is provided with a plurality of positioning grooves that cooperate with dead bolt, and dead bolt can be fastened in any one positioning groove, when dead bolt is fastened in the positioning groove, back support bar is in the lock state, put forward back support bar on this moment, dead bolt promptly withdraws from the positioning groove at place, realizes release.
Described dead bolt is provided with mounting groove, and pin is located in the top of mounting groove, and described stage clip is installed in the bottom of mounting groove, and its upper end withstands on the pin.
Described dead bolt is plugged in the bottom of back support bar, and fixes by rivet with back support bar, and the tongue of described dead bolt stretches out in the back support bar lower end, for cooperating with positioning groove on the locations.
Described locations is curved, and is arranged in the periphery of back support bar, and described a plurality of positioning grooves compartment of terrain is arranged on the intrados of locations.
The utility model has the advantages that: because the connecting element of back support bar and vehicle frame is by the pin pin joint in the utility model, and the pin-and-hole of back support bar is Long Circle, so back support bar not only can rotate around bearing pin, but also bearing pin moves up and down relatively.Back support bar moving downward or upward can make dead bolt snap in or withdraw from positioning groove, thereby realizes locking or release between back support bar and the vehicle frame, so the singlehanded angle of inclination that can the adjustment seat chair back of the utility model, and be easy to operate.In addition, structure of the present utility model is also extremely simple, not only greatly reduces productive costs, and has improved the market competitiveness.

The specific embodiment
Embodiment: as shown in Figures 1 to 4, a kind of doll carriage backrest adjustment mechanism, comprise vehicle frame 1 and back support bar 2, the connecting element 11 of described back support bar 2 and vehicle frame 1 is by pin 3 pin joints, the pin-and-hole 21 of above-mentioned back support bar 2 is a slotted hole, the bottom of back support bar 2 is provided with dead bolt 4, be provided with stage clip 5 between dead bolt 4 and the pin 3, be installed with the arc locations 12 that is arranged in back support bar 2 peripheries on the described connecting element 11, the compartment of terrain is furnished with a plurality of positioning grooves 121 that cooperate with dead bolt 4 on the intrados of this locations 12, dead bolt 4 can be fastened in any one positioning groove 121, when dead bolt 4 was fastened in the positioning groove 121, back support bar 2 was in the lock state, and put forward back support bar 2 on this moment, dead bolt 4 promptly withdraws from the positioning groove 121 at place, realizes release.
Above-mentioned dead bolt 4 with the concrete mounting means of back support bar 2 is: described dead bolt 4 is plugged in the bottom of back support bar 2, and with back support bar 2 by rivet 6 riveted and fixed, the tongue 42 of described dead bolt 4 stretches out in back support bar 2 lower ends, for cooperating with positioning groove 121 on the locations 12.
Concrete mounting means between above-mentioned dead bolt 4, stage clip 5 and the pin 3 is: described dead bolt 4 is provided with mounting groove 41, and pin 3 is located in the top of mounting groove 41, and described stage clip 5 is installed in the bottom of mounting groove 41, and its upper end withstands on the pin 3.
Because back support bar 2 and the connecting element 11 of vehicle frame 1 be by pin 3 pin joints in the utility model, and the pin-and-hole 21 of back support bar 2 be Long Circle, so back support bar 2 not only can rotate around bearing pin 3, but also bearing pin 3 moves up and down relatively.During the angle of inclination of adjustment seat chair back, put forward back support bar 2 on needing only, dead bolt 4 can withdraw from the positioning groove 121 at place, realize release (seeing Fig. 3 and shown in Figure 4), rotate back support bar 2 this moment again to suitable angle, and press down back support bar 2, and can make dead bolt 4 snap in the positioning groove 121 of relevant position, realize the locking (seeing Figure 1 and Figure 2) between back support bar 2 and the vehicle frame 1.Therefore, the singlehanded angle of inclination that gets final product the adjustment seat chair back of the utility model, easy to operate.In addition, structure of the present utility model is also extremely simple, not only greatly reduces productive costs, and has improved the market competitiveness.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.In addition to the implementation, the utility model can also have other embodiment.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the utility model scope required for protection.
